Kwang S. Kim is currently a Professor of chemistry, an Adjunct Professor in physics, and the Director of the Center for Superfunctional Materials (CSM) of UNIST. He is a Korea National Scientist. He received his Ph.D. degree from the University of California, Berkeley. After IBM Postdoctoral experience, he worked as a Research Professor and Visting Scientist at Rutgers University, MIT, and Columbia University. He had been a professor, Postech fellow, and director at POSTECH. He is a Fellow of the KAST and an elected member of ICQC. He received many awards including Korea Premium Science and Technology award, Fukui medal, and Mulliken lecture. He is serving as a Senior Editor of the Journal of Physical Chemistry (A, B, C) and board members of NPG Asia Materials, Journal of Computational Chemistry, Computational and Theoretical Chemistry, Chemical Physics Letters, Chemistry Letters, and WIRES Computational Molecular Science. His fields of research include investigations of density functional theory, ab initio calculations, nonequilibrium Green function theory, Monte Carlo and molecular dynamics simulations, first principles ground and excited-state molecular dynamics simulations, intermolecular interactions, clusters, molecular recognition, receptors, drug design, bioinformatics, biomolecules, nanomaterials, molecular devices, spintronics, and quantum computing.
Research Summary
Based on the sophisticated theoretical modeling with state-of-the-art super-computer aided nano-material design approaches, we better understand the intriguing molecular assembly phenomena and molecular self-engineering processes. This has allowed the design of new functional materials with intriguing molecular architectures which are host to a range of new chemistry and physics. Subsequently, we have demonstrated the successful synthesis and fabrication of nano-materials and devices such as nanolenses, graphene sheets, organic nanotubes, and molecular sensors/sorters.

Our research can be outlined as 1) Theoretical/computational design and 2) Experimental demonstration of functional nanomaterials/nanodevices toward new chemistry and physics:

Theoretical/computational chemistry/physics
Density functional theory, ab initio theory, molecular dynamics, statistical thermodynamics, molecular recognition, self-assembly, transport phenomena, nonequilibrium thermodynamics, entanglement perturbation theory

Experimental Nanosciences
Functional molecules/materials, molecular sensing, molecular engineering, nano electronic/spintronic/photonic devices, light harvesting, photosynthesis, green chemistry, gas storage, energy materials/devices, DNA sequencing, molecular robots

Our main research focus has been the theoretical design and experimental development of novel functional molecular/material systems and molecular/nano devices through the understanding of molecular functional mechanisms and assemblies. In sharp contrast to conventional host-guest chemistry, the guests in our case include photons, electrons, and protons as well as molecules and ions. Thus, our study includes understanding the static and dynamic properties of nanomaterials by elucidation of matter-photon/electron interactions.
